In the year 2004 181 samples, 98 head lettuce, 42 iceberg lettuce and 41 spinach samples, all vegetables subjected to EU Regulation466/2001, were analysed for nitrate. The EU nitrate limits for lettuce are in force in the Netherlands. Generally, the nitrate levels of lettuce and spinach are in good compliance with the EU limits for lettuce and with the Dutch derogation limits for spinach, respectively. Iceberg lettuce appeared to contain remarkably less nitrate than the other varieties of lettuce. These conclusions are the same as in former years. The tendency of decreasing nitrate levels in spinach, observed since 2001, seems to be stopped.
